SPINNING AND TWISTING MACHINE Filed Oct. 30, 1950 2 Sheets-Sheet 2INVENTOR Patented July 5, 1932 UNITED STATES PATENT OFFICE IRVING- R.ROWE, F STONINGTON, CONNECTICUT, ASSIGNOR TO THE ATWOOD MACHINE COMPANY,OF STONINGTON, CONNECTICUT, A CORPORATION OF NEW JERSEY SPINNING ANDTWISTING MACHINE Application filed October 30, 1930. Serial No. 492,152.

This invention relates to improvements in spinning and twisting machinesand more particularly to the driving mechanism for the endless beltswhich actuate the spindles or other devices.

One of the objects of the invention is to provide means for changing thesurface speed of the driving belts without effecting the position of thedriven and idler pulleys.

Another object is to provide a mechanism for adjusting the motor and itsdriving means with respect to the main driving pulley of the belt.

Another object is to provide means for automatically maintaining apredetermined tension on the driving belt without effecting the.positionof the belt with respect to the spindles actuated thereby.

Another object is to provide a drlving mechanism, the arrangement ofwhich is such rangement as to readily and easily remove or replace thedriving belts, when desired.

Another object is to provide certain improvements in the form,construction and arof the several parts whereby the above named andother ob ects may effectively be attained.

A practical embodiment of my invention is represented in theaccompanying drawings,

39 in which Fig. 1 represents a detail side elevation, partly insection, of the driving end of a spinning and twisting machine, havingtwo deckso-f spindles superposed in the frame, and my improved drivingmechanism applied thereto;

Fig. 2 represents a horizontal section taken in the plane of the lineIIII of Fig. 1, look- 1 single driven shaft 3 common to both decks.

The end frame 4 has secured thereto upper and lower pairs of rods orpipes 5, 6, respectively, which rods are disposed on opposite sides ofthe frame and extend throughout the length of the machine. It is to beunderstood that a similar end frame serves to support the opposite endof the several rods. The spindles of each deck are denoted by 7, andeach spindle comprises a whirl 8 mounted in a bearing 9 carried by asuport 10 secured to a pair of rods by a bolt 11.

Each deck of spindles is actuated by an endless belt 12 which is guidedaround an idler pulley 13,'an idler take up pulley 14 and a drive pulley15. The idler pulley 13 is mounted in a bracket 16 fixed to the endframe 4 while the idler pulley 14 is movably mounted in a bracket 17also carried by the frame. The drive pulley 15 is fixed to the verticalshaft 3, which is stepped in a lower bearing 18 and an upper bearing 19,both of which bearings are secured to the end frame 4. The idler take uppulley 14 is mounted to move in the bracket 17 by means of a plate 20mounted to slide in guide rails 21, 22 of the bracket 17, which plate ismoved horizontally in the guide rails by means of a rack 23 fixedontheunderside of the plate 20 and a pinion 24 carried by a shaft 25, whichis journaled in a bracket 26 secured to and depending from the guiderail22. The end of the shaft 25 has secured thereto a spring actuated pawl27 arranged to 'coact with ratchet teeth 28 on the face of a member 29mounted to rock on a hub 30 of the bracket 26. The coaction of theratchet teeth on the member 29 with the pawl on the shaft 25 adjustablylocks the shaft 25 to the member 29. The memmr 29 is also provided withan arm 31 adapted to receive a weight 32 adjustably secured thereon bymeans of set screws 33. Thus it will be seen that the weighted arm 31tends to rock the member 29 in its bracket 26 so that the ratchet teeth28 will exert pressure on the pawl 27 which, in turn, rotates the shaft25 and its plnion 24 while the pinion transmits its motion to the rack23 on the plate 20. By the outward movement of the plate 20, the pulley14,

which is carried thereby, will serve to maintain a frictional contactwith the belt, while the weighted arm 31 through its ratchet and pawlconnection with the shaft 25, pinion 24, and rack 23, tends toautomatical y hold a predetermined tension on the belt.

Motion is imparted to the vertical shaft 3 by means of a motor 34 havingits driving shaft 35 provided with a gear 36 removably mounted thereon,which gear 36 meshes with a gear 37 fixed on the shaft 3.

The motor 34 is secured at one side toa plate 38 by means of bolts 39and nuts 40, and has a slidable adjustment thereon by means of elongatedslots 41 through which the bolts 39 pass. As a means for guiding themotor 34 on the plate, legs 42 on the motor are provided with grooves43, each of which is arranged to receive a key 44 carried by the plate38. This plate 38 is mounted on a rod 45 by means of straps 46, 4'7, oneend of which rod is bolted at 48 to the frame 4, while the other end islocked at 49 in an upright 50 located within the frame of the machine.The motor is further provided with a lug 51 having ears 52, 53, whichare arranged to straddle a rod 54 bolted between the frame 4 and theupright 50. Adjusting screws 55, 56 are threaded in the ears 52, 53 andarranged to impinge upon the rod 54 so as to provide a means by whichthe motor 34 with its drive shaft 35 and gear 36 may be readily moved toproperly aline the gear 36 with the gear 37 on the shaft 3.

The surface speed of the belt 12 may be readil changed by removing thegear 36 from its shaft 35 and substituting therefor a gear of larger orsmaller diameter. This is accomplished by loosening the nuts 40 on thebolts 39, so that the bolts are free to slide in the slots 41 in theplate 38 and the legs 42 with their grooves 43 capable of being slid onthe keys 44. This movement of the motor disengages the gear 36 with thegear 37. \Vhen the gear 36 has been removed from the motor shaft andreplaced by another gear of larger or smaller diameter, the motor andits legs may again be slid on the keys 44 until the replaced gear andthe gear 37 are enmeshed, after which the nuts 40-are tightened on thebolts 39 and the motor locked to the plate 38.

From the foregoing it will be seen that a constant tension is applied tothe belt 12, and the same tension maintained at all speeds. Furthermore,by changing the gears to increase or diminish the surface speed of thebelt, the tension and position of the driven and idler pulleys aremaintained.

It is also evident from the construction and arrangement of themechanism that the driving belts may be removed or replaced whendesired, without disengaging the driving gears, so that the samesurface-speed may be maintained for any belt applied thereto.

It is obvious that various changes ma be resorted to in the form,construction an arrangement of the several parts without departing fromthe spirit and scope of my invention; and hence, I do not intend to belimited to the details herein shown and described except as they may beincluded in the claims.
